Abstract

We demonstrate a compact and low-loss 1 × 2 power splitter that efficiently splits and couples light from one strip to two slot waveguides. The splitter is optimized over a broad wavelength span ranging from 1.3 to 1.7

${\mu }$

m through finite difference time domain simulations. The splitter junction footprint is only 2.00 × 1.61

${\mu }$

m. The structure does not require an adiabatic transition region and is compatible with standard commercial silicon photonic fabrication processes. Experimental results show an insertion loss of less than 0.7dB for the TE polarization.

一种紧凑的宽带分频器，用于连接条形波导和槽形波导

我们展示了一种紧凑、低损耗的1 × 2功率分配器，它能有效地将光从一条波导分割和耦合到两个槽波导。通过时域有限差分仿真，在1.3 ~ 1.7 ${\mu}$m的宽波长范围内对分配器进行了优化。分路器结占地面积仅为2.00 × 1.61 ${\mu}$m。该结构不需要绝热过渡区，并且与标准的商用硅光子制造工艺兼容。实验结果表明，TE极化的插入损耗小于0.7dB。
